, IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 149,314, dated April'j, 1874; 'applicationiiled May 31,1873.

To all whom it may concern:

' Be it known that I, HARRISON JoNEs, of Ripley, in the county of Somerset and State of Maine, have invented a new and valuable Improvement in Flows; and I do hereby declare that the following is a full, clear, and

of my improved plow by a top view. Fig. 2

is an elevation of the same. Figs. 3 and 4 are detailed views of the same.

My invention relates to plows; and it consists in the novel construction and arrangement of the parts, as will be hereinafter more fully described and claimed.

The object of my invention is to make a plow which workseasily and without clogging, and wears very little in proportion to the wear of other plows differently constructed.

In the drawings, A represents a plow-beam, of ordinary construction, to the front end of which a couple of draw-bars, B, with Tshaped ends b are attached, their front ends being united into a head bearing an inclined or diagonal clevis, (l. The said draw-bars are fastened to the plow-beam with two bolts, N, of

which the rear one may be changed into the different hole b in the T-shaped ends I) of the draw-bars, the front bolt 12 remaining in its place, whereby the clevis and the truck-pulley G, which is attached to the draw-bars by two pendent arms, B, are either lowered or raised and the plow is either caused to plow less or more below the surface of the ground. An independent adjustment of the pulley D is afforded by a number of holes, b in the arms B, into which the bearing-bolt d of the pulley may be inserted. A U-shaped bolt, E, with a dogplate, I, and two nuts, 0, secures the plow to the beam A by passing through the standard G under its head-plate g. The standard G is united with the mold-board H, which has a warped surface, consisting of straight horizontal lines, so arranged that a number of vertical sections result in a number of straight section-lines with different inclinations, beginning with a very pointed angle at the front of the plow and ending with an obtuse angle be hind. In front of the standard G, between two bearings, g and h, an upright rollerof conicalshape, I, isinserted with its small diameter down. The land-sideK and the point L are attached to the mold-board by an angu lar inner clamp-plate, M, and clamp-screws The point L consists of the pointproper l,- which has a cuttingedge in front and a knife? shaped ridge, l, on the land-side, which suddenly rises, forming a broad blade,'l with-a cutting-edge in front. From the base of the blade 1 the metal forms the continuation of the mold-board until near the base of the plow, where it ends with a horizontal knife, 1 The land-side K is inclined fromits base up to ward the mold-board, and it is provided at thebase with a rib, 10, which tapers off toward the front of the plow. The mold-board I:I-for n 1s the continuation of the land-side from their junction toward the point L, where it forms a sty, by allowing the point to project. .The ridge 1 and the cutting-blade l have the same inclination toward the mold-board as the landside, which greatly facilitates the molding and casting of the same parts without impairing their efiiciency.

In repairing or exchanging the abovesaid parts for new ones there is no necessity for a very neat fit, as the said projections have to contend with all the side friction of the plow.

The formation of the mold-board H keeps the bottom side of the turned-up soil from crowding onto the metal and clogging it, thereby giving much less labor to the teams. The ridge Z serves to gradually and easily sever the soil-band from the remaining soil, and the blade 1 will bring the said operation to an abrupt termination when .it is time for the soil to leave the edge of the land-side. If the soil-band should be interrupted by breakage, or otherwise show a very rugged edge, and for that reason be very apt to run against the plow-standard, the roller I will be struck instead, and, by giving way to the thrust, will ward off the soil and throw it back on-thc mold-board.

To prevent the soil from olimbin g up against the roller 1, I make it conical with the large diameter above, whereby, on account of the difl'erence in the circumferential speed, the

The handles N. and 0 are connected by two wooden braces, n and o, the latter one forming" A- bolt, 1?, is passed through the beam A and the handle N, and fastened by two clamp-nuts, p, and, by being fastened in the same manner tothehandleOwiththenuts 0!, forms a very stiff and powerful connection between the two handles..- The, beam- A, by being fastened to. thegplgw-standard Without inserted bolts or melt d tarts i le t asst on as p s nd-the. le is, bei ag a ly in serves the purpose of.; -vcrtical adjustment and the purposeof horizontal adjustment, which two are an imperative necessitywhen the depth of the plowing varies, as the side pressure on the horizontal knife. l and on the lower part of the mold-board H tends more or less to throw the plow out of its. direction. I The horizontal knife Z is very thin, which facilitates the chillingpf the metal when cast, and which serves to make it enter the ground, and sever it with great ease asit meets the mold-board at an angle, The soil continues .its course at the angle of thecutting-edgeon the knife 1 without touching the greater part ofthe said knife and apart ofthe mold-board-near the-angle of meeting above described.

The-plow is essentially different from other plows on account of its length and the acute nessof the angles o f --the severing or cutting parts, which, far from being disadvantageous, makes my plow, in connection with its otherwise peculiar construction, a very perfect and light implement.

"What I claim as my invention, and desire to secure by Letters Patent, is-.

On a plow-beam, A, of common construction, the strap B with the diagonal clevis (J,

the T-shaped ends b with adjusting-holes b and bolts 7), the arms B with adjusting-holesv b, and the truckpu]ley D, substantially as specified.

2. -The plow-point cast in one piece, having the. point}, the ground-knife P, with horizontal cutting-edge, the ridge 1 and the blade Z joined. to the mold-board by forming lateral angles or corners with the same, substantially as and for the purposes described.

3. In a plow, the arrangement of the clevis O in a diagonal position, for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
